- dools 3y agoIt's also how blockchains work: "A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes.[1][2][3][4] Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves)" https://en.wikipedia.org/wiki/Blockchain https://en.wikipedia.org/wiki/Blockchain
- ben-schaaf 3y agoYes, but without the "distributed ledger" and thus consensus protocol it's no longer a blockchain.
